Abstract

La presente descripción provee un método y sistema para transmitir una señal de referencia de posición, que incluye: adquirir una secuencia de señal de referencia de posición actualmente necesitada (PRS), con una longitud de 2xNPRSRB, en donde NPRSRB es un ancho de banda de PRS configurado por señalización de capa alta, y representado por la unidad de un bloque de recurso; determinar la posición de la secuencia de la PRS en un bloque de recurso físico; y transmitir la secuencia de PRS adquirida en la posición determinada; con el método de la presente descripción, una secuencia de PRS actualmente necesitada se adquiere directamente, o al principio, una secuencia de PRS con la longitud máxima se genera, y después la secuencia de PRS actualmente necesitada es interceptada a partir de la secuencia de PRS con la longitud máxima; la presente descripción asegura que una secuencia efectiva de PRS puede ser adquirida en cualquier circunstancia, lo que asegura la realización de la función de posicionamiento de la PRS.
